I'm in the US. On about 1 in 10 calls, I'm not receiving the number of the caller. From an Asterisk perspective, it looks like CALLERID(num) is "LINE" instead of a phone number. In the OBi110's Call History, I see Peer Number "LINE" that I think corresponds to what I'm seeing from Asterisk.
My OBi110's LINE port uses the default CallerIDDetectMethod, FSK(Bell 202). I've experimented with RingDelay values up to 8000, not seeing any difference.
Are there any other parameters I should be experimenting with to try to achieve reliable caller ID reception?
